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