Presentation

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

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

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