Dear all, Let X be a nonempty finite set and let P be an arbitrary partition of X. Denote by T(X, P) the semigroup of transformations preserving partition P.
Can anybody tell me a GAP code, if any, to compute the size of the subsemigroup of T(X, P) consisting of those transformations whose image intersects every block of P. Thanks in advance for your assistance. -- Sincerely, *------------------------------------------* *Shubh N.
