Presentation

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

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

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