Add $28 v$ to both sides:
$- 28 v - 12 + 28 v = 36 - 4 v + 28 v$

In a QM text I am using (Sakurai 2nd edition 'Modern Quantum Mechanics'), he describes two rotation groups, namely the $\mathrm{SO}(3)$ rotation group and $\mathrm{SU}(2)$ rotation group (unitary unimodular group).
He defines $\mathrm{SO}(3... | open-web-math/open-web-math | |

# Unimodular lattice
Not to be confused with modular lattice.
In geometry and mathematical group theory, a unimodular lattice is an integral lattice of determinant 1 or −1. For a lattice in n-dimensional Euclidean space, this is equivalent to requiring that the volume of any fundamental domain for the lattice be 1.
