Magma[TransportStructure] - produce an isomorphic copy of a magma

Calling Sequence

TransportStructure( dst, src, p )

Parameters

dst

-

Array; array into which to copy structure from src

src

-

Array; source magma whose Cayley table is to be moved

p

-

permlist; permutation of 1..n to effect the isomorphic copy

Description

• 

The TransportStructure( 'dst', 'src', 'p' ) command uses the permutation p to produce an isomorphic copy of the source magma src in the array dst, in such a way that the permutation p is then an isomorphism from src to dst.

• 

A more convenient, but less efficient interface to this functionality is provided by the IsomorphicCopy command, which allocates storage for the resulting Cayley table automatically.

Examples
