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