Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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