typedef NPerm4 regina::NPerm 
A legacy typedef provided for backward compatibility only.
REGINA_API const int regina::edgeEnd[6] 
edgeEnd[k]
is the vertex of a tetrahedron at which edge k
of the tetrahedron ends.
k
must be between 0 and 5 inclusive. The resulting vertex number will be between 0 and 3 inclusive.
Note that edge numbers of opposite edges will always add to 5. You are guaranteed that edgeStart[e]
will always be smaller than edgeEnd[e]
.
edgeEnd[i]
is now NEdge::edgeVertex[i][1]
). Users are advised to switch to NEdge::edgeVertex instead, since the old regina::edgeStart and regina::edgeEnd will eventually be removed in some future version of Regina. REGINA_API const int regina::edgeNumber[4][4] 
edgeNumber[i][j]
is the number of the edge linking vertices i
and j
in a tetrahedron.
i
and j
must be between 0 and 3 inclusive and may be given in any order. The resulting edge number will be between 0 and 5 inclusive.
Note that edge numbers of opposite edges will always add to 5.
REGINA_API const int regina::edgeStart[6] 
edgeStart[k]
is the vertex of a tetrahedron at which edge k
of the tetrahedron begins.
k
must be between 0 and 5 inclusive. The resulting vertex number will be between 0 and 3 inclusive.
Note that edge numbers of opposite edges will always add to 5. You are guaranteed that edgeStart[e]
will always be smaller than edgeEnd[e]
.
edgeStart[i]
is now NEdge::edgeVertex[i][0]
). Users are advised to switch to NEdge::edgeVertex instead, since the old regina::edgeStart and regina::edgeEnd will eventually be removed in some future version of Regina.
