It is n ot known whether this can also be done with fewer multiplications. However \, there are several mutually inequivalent ways of doing the job with 23 m ultiplications. We extend this list considerably by providing more than 13 000 new and mutually inequivalent schemes for multiplying 3 3-matrices us ing 23 multiplications. This is joint work with Marijn Heule and Martina S eidl.\n LOCATION:https://researchseminars.org/talk/ExpMath/2/ END:VEVENT END:VCALENDAR
