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