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