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