Presentation

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

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

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