Presentation

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

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

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