Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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