Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 512

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

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