Directions and parking

Click here for directions to the parking garage next to the King Library; the lot is on the NE corner of 4th & San Fernando, and the library is on the SE corner. Parking is $5 for the entire day. Please talk with your local BAD Math Organizer about carpooling, or please e-mail Tim Hsu ( if you're interested in carpooling and you don't have a natural group to join.

Taking public transit to BAD Math Day

It is possible but nontrivial to take public transit to SJSU on BAD Math Day. For details and schedules, get directions from the parking garage map and click on the bus icon, which should suggest several public transit routes.

From SF or the East Bay: Probably the best approach is to take BART to Fremont and transfer to VTA Bus 181. One-way travel time is around 2 hours from the East Bay, more from SF.

From Santa Clara Valley (from Menlo Park and Palo Alto to San Jose and surroundings): Depending on where you live, you should be able to take the bus or light rail to downtown San Jose; see the VTA website for schedules and details.

The 26th BAD Math Day is generously sponsored by the D. E. Shaw group:

BAD Math Days are one-day meetings aimed at facilitating communication between researchers and graduate students of discrete mathematics around the San Francisco Bay Area. These days happen twice a year and strive to create an informal atmosphere to talk about discrete mathematics. The term "discrete mathematics" is chosen to include at least the following topics: Algebraic and Enumerative Combinatorics, Discrete Geometry, Graph Theory, Coding and Design Theory, Combinatorial Aspects of Computational Algebra and Geometry, Combinatorial Optimization, Probabilistic Combinatorics, and Combinatorics in Mathematical Physics.
