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