Odd, positive-definite, integral, unimodular lattices N of rank 24 were classified by Borcherds. There are 273 isometry classes of such lattices. Associated to them are vertex superalgebras \$V_N\$ of central charge c=24. We show that at least 267 of these vertex operator superalgebras contain an N=4 superconformal subalgebra of central charge \$c'=6\$. This is achieved by studying embeddings \$L+\subseteq N\$ of a certain rank 6 lattice L+.

It is shown that every weak Jacobi form of weight zero and index one on a congruence subgroup of the full Jacobi group can be decomposed into N = 4 superconformal characters. Additionally, a simple
