Let ρ(s) be a fixed infinitely differentiable function defined on R+=[0,) having the properties: (i) ρ(s)0, (ii) ρ(s)=0 for s1, and (iii) Rmδn(x)dx=1 where δn(x)=cmnmρ(n2r2) and cm is the constant satisfying (iii). We overcome difficulties arising from computing lδn and express this regular sequence by two mutual recursions and use a Java swing program to evaluate corresponding coefficients. Hence, we are able to imply the distributional product rklδ for k=1,2, and l=0,1,2, with the help of Pizetti's formula and the normalization.
