Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 28 points:

(6,9)(7,11)(21,22)(23,26)(24,27)(25,28);(13,14)(15,18)(16,17)(19,20)(21,23)(22,25)(24,28)(26,27);(2,3)(14,17)(18,19);(6,9)(10,12)(21,23)(22,26)(24,28)(25,27);(1,2,4,3)(5,6,8,9)(7,12,11,10)(13,14)(15,19)(16,17)(18,20)(21,23)(22,26)(24,28)(25,27);(1,3,4,2)(5,7,8,11)(6,10,9,12)(13,15,16,20)(14,18,17,19)(21,22)(23,25)(24,27)(26,28)
