Presentation

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

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

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