Presentation

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

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

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