Presentation

minimal degreeμ(G) = 25
transitive degreeμt(G) = 136

A minimal faithful permutation representation — 2 generators on 25 points:

(1,2,3,4,5,6,7,8)(9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25);(2,8)(3,7)(4,6)(10,25)(11,24)(12,23)(13,22)(14,21)(15,20)(16,19)(17,18)

Polycyclic presentation:
