Presentation

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

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

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