Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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