What is the next composite number?

If pn is the nth prime number. then what is the next composite number after say p24×p5 without actual calculation? (p24×p5+1 is p21p32p3) the first few composite numbers seem to follow no immediate pattern i.e. p21,p1p2,p31,p22,p21p2,




For example given the consecutive composite numbers pk1j1pk2j2pknjn and pn1m1pn2m2pnrmr what is the mapping from ((j1,k1),(j2,k2)(jn,kn))((m1,n1),(m2,n2)(mr,nr))
