Presentation

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

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

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