Presentation

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

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

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