Presentation

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

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

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