InitPseudoRandom( G, length, n )
InitPseudoRandom( module, length, n )
InitPseudoRandom takes as input either a matrix group G, or a
G-module module. It constructs a list (or seed) of elements which
can be used to generate pseudo-random elements of the matrix group or
G-module. This seed is stored as a component of the supplied record and
can be accessed using
InitPseudoRandom generates a seed of length elements containing
copies of the generators of G and performs a total of n matrix
multiplications to initialise this list.
The quality of the seed is determined by the value of n. For many
applications, length = 10 and n = 100 seem to suffice; these are the
defaults used by
The algorithm is described in .
