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