Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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