#### 5Question: In a brain-computer interface system, 6 distinct neural signals are grouped into 2 clusters for signal translation. If the clusters are indistinguishable and each cluster must contain at least one signal, how many ways can the signals be grouped?

**How Many Ways Can 6 Neural Signals Be Grouped Into Indistinguishable Clusters?**
*Understanding signal clustering in brain-computer interfaces* In modern neuroscience and digital health, brain-computer interface (BCI) systems increasingly rely on classifying neural activity into meaningful clusters. One critical challenge involves dividing six distinct neural signals into two non-identical, non-empty groups—where the order of the clusters doesn’t matter. As BCI technology advances, researchers and developers are seeking precise, reliable ways to organize and interpret neural data, especially in applications like neuroprosthetics, cognitive monitoring, and brain-controlled communication tools. For curious users exploring how these systems function behind often-discussed breakthroughs, a key question emerges: How many distinct ways can six unique neural signals be grouped into two clusters, with no empty groups allowed? --- **Why This Topic Matters in the US and Beyond**
