Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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