Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

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