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