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