Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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