produce an isomorphic copy of a magma
TransportStructure( dst, src, p )
Array; array into which to copy structure from src
Array; source magma whose Cayley table is to be moved
permlist; permutation of 1..n to effect the isomorphic copy
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.
m ≔ 1|2|3,2|3|1,3|1|2
p ≔ 2,1,3
m2 ≔ TransportStructure⁡Array⁡1..3,1..3,':-order'=':-C_order',':-datatype'=':-integer'4,m,p
The Magma[TransportStructure] command was introduced in Maple 15.
