Lascoux, Leclerc and Thibon (1997) [9] introduced a family of symmetric polynomials, called LLT polynomials. We prove a q-multinomial expansion of the coefficients of LLT polynomials in the case where mu = %26lt;br%26gt;[GRAPHICS] %26lt;br%26gt;and define a q-analog of a sum of the plethysm multiplicities.
