Presentation

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

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

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