Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

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

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