In knot theory, the 6₂ knot is one of three prime knots with crossing number six, the others being the stevedore knot and the 6₃ knot. This knot is sometimes referred to as the Miller Institute knot,^[1] because it appears in the logo^[2] of the Miller Institute for Basic Research in Science at the University of California, Berkeley.

The 6₂ knot is invertible but not amphichiral. Its Alexander polynomial is

${\displaystyle \Delta (t)=-t^{2}+3t-3+3t^{-1}-t^{-2},\,}$

its Conway polynomial is

${\displaystyle \nabla (z)=-z^{4}-z^{2}+1,\,}$

and its Jones polynomial is

${\displaystyle V(q)=q-1+2q^{-1}-2q^{-2}+2q^{-3}-2q^{-4}+q^{-5}.\,}$^[3]

The 6₂ knot is a hyperbolic knot, with its complement having a volume of approximately 4.40083.
