Grammar 5 is a context-free grammar for the painted cactus language that uses <math>\mathfrak{Q} = \{ \, ^{\backprime\backprime} \, S' \, ^{\prime\prime}, \, ^{\backprime\backprime} \, T \, ^{\prime\prime} \, \},</math> with <math>\mathfrak{K}</math> as listed in the next display.

Finally, it is worth trying to bring together the advantages of these

diverse styles of grammar, to whatever extent that they are compatible.

To do this, a prospective grammar must be capable of maintaining a high

level of intermediate organization, like that arrived at in Grammar 2,

while respecting the principle of intermediate significance, and thus

accumulating all the benefits of the context-free format in Grammar 5.

A plausible synthesis of most of these features is given in Grammar 6.
