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