Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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