Calling Sequence

SubMagmaClosure( gens, m )

Parameters

gens

-

set of elements of m; subset of {1,2,...,n}.

m

-

Array representing the Cayley table of a finite magma of order n

Description

• 

The SubMagmaClosure( gens, m ) command returns the set of elements of the magma m generated by the set gens of elements of m. This is the smallest submagma of m containing the set gens.

Examples

with( Magma ):

m := << 3, 5, 3, 4, 3 ; 2, 5, 2, 3, 3 ; 4, 3, 1, 4, 2 ; 3, 2, 1, 1, 1 ; 5, 2, 4, 5, 4 >>;
