// W-graph data for G2
//
// Each of the lines below corresponds to a vertex w of the W-graph of G2.
// The individual datums in each line are separated by colons. They
// are interpretable as follows:
//   datum[1] := integer labeling the vertex element w
//   datum[2] := length of w
//   datum[3] := a list of indexes of simple roots that are left descents of w
//   datum[4] := a list of pairs [j,m]; each pair corresponding to an edge
//                i->j with multiplicity m in the W-graph
