What Is the Number of All Possible Relations/intersections of N Sets? 1

Disclaimer: Not an answerI would like to think about this problem not as sets, but as elements in a partial order. Suppose all sets are different. Define $mathscrP = langlemathscrP(bigcup_n A_n), subseteq

angle$ as the partial order generated bay subset relation on all "interesting" sets.Define the operation $cap$ on $mathscrP$ as$$ C = Acap B iff C = sup_subseteq D: Dsubseteq A wedge Dsubseteq B $$which is well defined because of, well, set theory....The question could be then stated as:Given the sets $A_n$, let $mathscrG$ the subgraph of $mathscrP$ generated by the $A_n$ and closed under the $cap$ operation. How many non-isomoprhic graph can we get?

Known difference sets

In many constructions of difference sets the groups that are used are related to the additive and multiplicative groups of finite fields. The notation used to denote these fields differs according to discipline. In this section, G F ( q ) displaystyle

m GF(q) is the Galois field of order q displaystyle q , where q displaystyle q is a prime or prime power. The group under addition is denoted by G = ( G F ( q ) , ) displaystyle G=(

m GF(q),) , while G F ( q ) displaystyle

m GF(q)^* is the multiplicative group of non-zero elements. Paley ( 4 n 1 , 2 n 1 , n 1 ) displaystyle (4n-1,2n-1,n-1) -difference set:Let q = 4 n 1 displaystyle q=4n-1 be a prime power. In the group G = ( G F ( q ) , ) displaystyle G=(

m GF(q),) , let D displaystyle D be the set of all non-zero squares.Singer ( ( q n 2 1 ) / ( q 1 ) , ( q n 1 1 ) / ( q 1 ) , ( q n 1 ) / ( q 1 ) ) displaystyle ((q^n2-1)/(q-1),(q^n1-1)/(q-1),(q^n-1)/(q-1)) -difference set:Let G = G F ( q n 2 ) / G F ( q ) displaystyle G=

m GF(q^n2)^*/

m GF(q)^* . Then the set D = x G | T r q n 2 / q ( x ) = 0 displaystyle D=xin G|

m Tr_q^n2/q(x)=0 is a ( ( q n 2 1 ) / ( q 1 ) , ( q n 1 1 ) / ( q 1 ) , ( q n 1 ) / ( q 1 ) ) displaystyle ((q^n2-1)/(q-1),(q^n1-1)/(q-1),(q^n-1)/(q-1)) -difference set, where T r q n 2 / q : G F ( q n 2 ) G F ( q ) displaystyle

m Tr_q^n2/q:

m GF(q^n2)

ightarrow

m GF(q) is the trace function T r q n 2 / q ( x ) = x x q x q n 1 displaystyle

m Tr_q^n2/q(x)=xx^qcdots x^q^n1 .Twin prime power ( q 2 2 q , q 2 2 q 1 2 , q 2 2 q 3 4 ) displaystyle left(q^22q,frac q^22q-12,frac q^22q-34

ight) -difference set when q displaystyle q and q 2 displaystyle q2 are both prime powers:In the group G = ( G F ( q ) , ) ( G F ( q 2 ) , ) displaystyle G=(

m GF(q),)oplus (

m GF(q2),) , let D = ( x , y ) : y = 0 or x and y are non-zero and both are squares or both are non-squares . displaystyle D=(x,y)colon y=0text or xtext and ytext are non-zero and both are squares or both are non-squares.

Live sets

The band played a series of 10 new songs during their first tour, with 13 in total. Three of these were Feeder 'covers', these were "Tangerine", "Sweet 16" and "Descend". Grant Nicholas told XFM that 25 songs have been recorded. On their second tour the Feeder 'covers' were "Women in Towels", "Shade", "Tangerine", "Sweet 16", "Lost and Found", "Descend" and "Godzilla". For one date the band performed a cover of the Nirvana track "Breed", which they have performed in the past as Feeder. "World Asleep" was on setlists for the second tour, but was never performed. Every track played live as Renegades has appeared on the album, although "City in a Rut" was only performed at Edinburgh on the second tour
