Presentation

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

A minimal faithful permutation representation — 4 generators on 26 points:

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

Polycyclic presentation:
