A heterogeneous collection of computistical texts and tables titled In honomate filii redemptoris cosmi a m(alo) (or am(en)), including in particular:
This codicological unit appears to be incomplete and the last folio (284v), which concerns finger-reckoning, is damaged and now nearly illegible.

|Connection with Brittany|
This heterogeneous computistical collection presents strong Breton features. In particular:
Holtz has suggested that this codicological unit of Lat. 6400B was written in a Breton scriptorium (Holtz and Lambert 1986: 187); some clues, however, rather indicate that this MS may have been copied from a Breton exemplar in a (North-)Western Frankish centre—perhaps at Fleury, which is the provenance of the other units of the miscellaneous codex now bearing the shelfmark Lat. 6400B (cf. Carey 1923: 96–7; LF BF1074–9, esp. BF1078). The most significant elements suggesting that this MS was produced outside of Brittany are:
In any case, there is no doubt that this codicological unit must date from the tenth century. The argumentum for the annus Domini at fol. 252v points to a range between AD 972 and 986, but this is because it was clearly updated by a later scribe; therefore, this argumentum actually fixes AD 972 as a terminus ante quem (other argumenta point to dating clauses in the late ninth century, but these were probably copied from an exemplar). The computistical table at fol. 273r covers the years 931–949, so that the MS may have been produced within this chronological range (and perhaps closer to the beginning of this particular 19-year cycle). Alternatively, if this table was copied faithfully from the exemplar, without updates, the MS may then have been written not long after AD 949. In any case, its script seems to point to a date not too late in the tenth century.
The computistica found in this MS present numerous features of interest and deserve to be studied in detail, especially insofar as they exhibit many points of contact with Early Medieval Irish computistical thought. Indeed, fols 274r–284r preserve a long section from the Computus Hibernicus Parisinus of AD 754, an Irish tract that survives only in this MS and in a few folios of Angers, BM, MS 476. Moreover, it is highly significant that some parts of the Computus of AD 754 match contents that occur elsewhere only in Paris, BnF, Lat. 7418A—a MS from eleventh-century Landévennec—and in the early ninth-century codex Laon, BM, 422. There is no doubt that this codicological unit of Lat. 6400B is a key witness for the circulation of Irish computistica in Early Medieval Brittany and for the reconstruction of the route of transmission of such texts between Ireland and the Carolingian empire.
