Presentation

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

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

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