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