Query: Exceptional M-brane sigma models and $\eta$-symbols   We develop the M-brane actions proposed in arXiv:1607.04265 by using
$\eta$-symbols determined in arXiv:1708.06342. Introducing $\eta$-forms that
are defined with the $\eta$-symbols, we present U-duality-covariant M-brane
actions which describe the known brane worldvolume theories for M$p$-branes
with $p=0,2,5$. We show that the self-duality relation known in the double
sigma model is naturally generalized to M-branes. In particular, for an
M5-brane, the self-duality relation is nontrivially realized, where the Hodge
star operator is defined with the familiar M5-brane metric while the
$\eta$-form contains the self-dual 3-form field strength. The action for a
Kaluza-Klein monopole is also partially reproduced. Moreover, we explain how to
treat type IIB branes in our general formalism. As a demonstration, we
reproduce the known action for a $(p,q)$-string.
