  This paper introduces inter-order formulas for partial and complete moments
of a Student $t$ distribution with $n$ degrees of freedom. We show how the
partial moment of order $n - j$ about any real value $m$ can be expressed in
terms of the partial moment of order $j - 1$ for $j$ in $\{1,\dots, n \}$.
Closed form expressions for the complete moments are also established. We then
focus on $L_p$-quantiles, which represent a class of generalized quantiles
defined through an asymmetric $p$-power loss function. Based on the results
obtained, we also show that for a Student $t$ distribution the
$L_{n-j+1}$-quantile and the $L_j$-quantile coincide at any confidence level
$\tau$ in $(0, 1)$.
