744 is a semiperfect number. It is also an abundant number.
The -invariant, an important function in the study of modular forms and Monstrous moonshine, can be written as a Fourier series in which the constant term is 744: where. One consequence of this is that 744 appears in expressions for Ramanujan's constant and other almost integers.
