[GAP Forum] I need help for programming

[TMU]

Dear programmers;
My name is A.Nejati. I want to construct a Coset Graph A=Cos(T,H,HbH)  in
GAP such that T = <a, b> , H = <a> , a = (3 11 9 7 5)(4 12 10 8 6) , b = (1
12)(2 7)(3 10)(4 8)(5 11)(6 9).  How done it is?
Sincerely yours



De nition: Let G be a group, H a subgroup of G, and S a subset of G. De
fine the coset graph of G with respect to H and S to be the directed graph
with vertex set [G : H] and such that, for any Hx Hy in V ,
Hx is connected to Hy if and only if yx-1 in HSH,
and denote the di-graph by Cos(G;H;HSH).
