-g NPerms
  Number of permutations (default is 2).

Perm
  Permutation base name.

Seed
  Seed point to start the orbit algorithm.

Stop
  Stop point for the orbit algorithm.

## Output Files

Script
  Result.

## Description

Given a set of generating permutations, this program find a product of the generators which maps a given point, Start, to a second given point, Stop. By default, the program works with two generators which are read from Perm.1 and Perm.2, respectively. You can specify a different number of permutations using the -g option.

The result is a list of numbers defining the result as a product in the generators. This file is a text file an can be read by GAP.
