Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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