Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 80

A minimal faithful permutation representation — 3 generators on 26 points:

(7,15)(11,16)(17,18,21,19,20)(22,23,24,26,25);(1,3)(2,7)(4,13)(5,12)(6,14)(8,11)(9,15)(10,16);(1,2,4,8,6,9,5,10)(3,11,12,7,14,16,13,15)(18,19,20,21)(23,24,25,26)

Polycyclic presentation:
