Original definition: "Number of dendriform generators of degree n of the algebra PQSym of parking quasi-symmetric functions."

The term 11378 is incorrect, but since it is cited in the preprint http://arxiv.org/abs/0806.3682, this sequence is kept for reference.

Sequence A122705 features the correct term 11278, as it also appears in http://arxiv.org/abs/math/0511200.
