Abstract
A conjecture that expresses the nth power of the cubic theta function in terms of Eisenstein series is formulated. It is an analogue of four conjectures of H. H. Chan and K. S. Chua for powers of . With the help of a computer, the conjecture is shown to be true for 6 ≤ n ≤ 100. It is conjectured that the result continues to hold for n > 100.
