Presentation

minimal degree	μ(G) = 25
transitive degree	μ_t(G) = 320

A minimal faithful permutation representation — 3 generators on 25 points:

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