Presentation

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

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

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