Presentation

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

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

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