GAP Manual: 61.25. MinBlocks

MinBlocks( module, B )

MinBlocks finds the smallest block containing the echelonised basis B under the action of the G-module module. The block system record returned has three components: the number of blocks, a block containing the supplied basis B, and a permutation group which describes the action of G on the blocks.

MinBlocks is called by IsPrimitiveMatrixGroup.

This function requires the package "smash" (see RequirePackage).
