The strongest signal is "Perimeter".Looking at `TOP_ACTIVATING_TEXTS`, I see "Area & Perimeter", "Area, perimeter, volume of simple shapes", "Area, perimeter, volume, angles", "Calculating area, perimeter, volume".The pattern is clearly related to geometry, specifically area and perimeter.The `TOP_POSITIVE_LOGITS` containing terms from different languages might suggest the neuron is sensitive to the *concept* of geometry regardless of language, or perhaps is looking for specific mathematical terms. However, the `MAX_ACTIVATING_TOKENS` is extremely strong for "Perimeter".The `TOKENS_AFTER_MAX_ACTIVATING_TOKEN` shows common punctuation marks that often follow a topic header or a definition.The simplest pattern that covers most of this is "perimeter math".perimeter math
