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