Quadrature Rule for Triangles
Hi I am in search of higher Quadrature Rule for Triangles (for numerical integration). I have implemented 13 point rule but i need higher points. Can any one have seen it in litrature? Thanks

Re: Quadrature Rule for Triangles
Please find:
P. Keast, "Moderatedegree tetrahedral quadrature formulas", Comp Meth Appl Mech and Eng, vol 55:339348(1986). Good luck. 
Re: Quadrature Rule for Triangles
Thanks Tony. Keast's paper only have rules for Tetra Hedra elements. I want the higher order rules for Triangles. I have the paper by G.R.Cowper who tabulated integration rules for triangle. But he went upto 13 point rule. I want higher rule. Waiting for reply
