Explore the Fink-Mao tie-tying grammar

The grammar that encodes the original 85 tie-knots enumerated by Fink and Mao is:

    [tie] ::= L [L_]
    [L_] ::= R [R_] | C [C_] | RCU
    [R_] ::= L [L_] | C [C_] | LCU
    [C_] ::= R [R_] | L [L_]

To start: choose by clicking the pale blue grammar symbol below to build a tieknot. The knot sequence will emerge to the left of the clickable symbol.
